The reader judges the small density is a new finding compared with the previous mammogram and recalls the patient for workup.

Look carefully at the CC view of 2012 and compare it with the 2013 image above. The positioning of the newest study is better than the previous image. On the 2012 CC view there is significant rotation of the breast medially relative to the axis of the nipple. There is significant less of the retromammary fat medially compared with laterally. It is quite possible the small density is just not on the image....
